The Mintex National Rally Championship is a test of man a machine. Eight rounds of demanding tarmac and forest stages pushed some of the country's best rally crews to their limit and beyond during 1991. Could Trevor Smith steer his Sierra Cosworth 4 X 4 to Championship victory at the fifth time of asking, or would he be pipped at the post by Hideaki Miyoshi? Could Steve Hill snatch the Group N showroom category for his Sierra Cosworth, or would the Mazda of Dom Buckley wrest it away from him? The answer to all these questions and more are revealed here, including exciting in-car footage from the cockpit of Smith's Sierra and interviews with the leading drivers.
